This memorial note for Professor Sanae-I Itoh presents her specific achievements in physics
research alongside her wider record of accomplishment in the field of magnetically confined …

Fusion research is driven by the applied goal of energy production from fusion reactions.
There is, however, a wealth of fundamental physics to be discovered and studied along the …

Geodesic acoustic modes, Alfvén eigenmodes, stationary and oscillating components of the
electric field, and their relations to plasma confinement have been studied. Theoretical …

We investigate spatial structures of turbulence and turbulent transport modulated by the
geodesic acoustic mode (GAM), from which the excitation mechanism of the GAM is …

Zonal flows (ZFs) and their oscillating counterpart, geodesic acoustic modes (GAMs), are
radially localized E× B plasma flows generated by non-linear turbulence interactions [1]. In …

Drift wave turbulence is known to self-organize to form axisymmetric macroscopic flows. The
basic mechanism for macroscopic flow generation is called inverse energy cascade …

Many years of fusion researches have shown that the energy and particle losses are
realized through several channels, eg via neoclassical losses. On top of that, turbulent …

Besides strong geodesic acoustic mode (GAM) activity, turbulence in the I-mode
confinement regime of ASDEX Upgrade exhibits two prominent features, the weakly …

Heavy ion beam probe (HIBP) is a unique tool for studying the electric potential and various
turbulence characteristics both in the core and at the edge of toroidal plasmas. The position …

Energetic ion driven Alfvén Eigenmodes (AEs) in the NBI-heated plasma at the TJ-II heliac
were studied by Heavy Ion Beam Probing (HIBP) in the core, and by Langmuir and Mirnov …
